Fix dangling pure CSS chunk imports when assetQueryParams is set by matthewp · Pull Request #16830 · withastro/astro

matthewp · 2026-05-21T19:55:46Z

Changes

Moves plugin-chunk-imports from renderChunk to generateBundle so it runs after Vite's CSS plugin cleans up pure CSS wrapper chunks. Previously, appending ?dpl=... query params during renderChunk broke Vite's regex-based /* empty css */ replacement, leaving dangling imports to deleted chunks that 404 at runtime.

Fixes #16520

Testing

New css-pure-chunk-query-params.test.ts with a Vue fixture where two async components share the same CSS import, forcing Rollup to create a shared pure CSS chunk. Verifies no JS imports reference deleted files, and that query params are still appended to surviving imports.

Docs

No docs needed — internal build pipeline fix with no user-facing API change.

For example, `'/project/[slug]': '/'` previously produced a confusing error pointing at `index.astro`. Astro now detects the parameter mismatch at config validation time and throws a clear `InvalidRedirectDestination` error naming the missing parameters. - [#16702](withastro/astro#16702) [`b7d1758`](withastro/astro@b7d1758) Thanks [@matthewp](https://github.com/matthewp)! - Fixes scoped styles from `.astro` components being dropped when rendered inside MDX content (`<Content />` from `render(entry)`) passed through a named slot using `<Fragment slot="X">`. The Fragment component now eagerly evaluates its slot contents to ensure propagating components register their styles before head content is flushed. - [#16823](withastro/astro#16823) [`3df6a45`](withastro/astro@3df6a45) Thanks [@astrobot-houston](https://github.com/astrobot-houston)! - Fixes missing CSS for conditionally rendered Svelte components in production builds - [#16836](withastro/astro#16836) [`3d7adfa`](withastro/astro@3d7adfa) Thanks [@LongYC](https://github.com/LongYC)! - Document compressHTML: "jsx" config is only available since Astro v6.2.0 - [#16864](withastro/astro#16864) [`334ce13`](withastro/astro@334ce13) Thanks [@cheets](https://github.com/cheets)! - Fixes a false-positive `Internal Warning: route cache overwritten` logged on every SSR request for dynamic routes </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Disabled by config.
